# Orbit Web Tools: AI-Agent Readiness Audit

> Orbit Web Tools: AI-Agent Readiness Audit is a paid API for AI agents from orbit-web.orbit-builder.workers.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-29).

Audits a website's readiness for AI agents by checking llms.txt, robots.txt crawler permissions, sitemap, x402, OpenAPI, MCP, A2A card, and security.txt, returning a 0–100 score.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability orbit-web-tools-ai-agent-readiness-audit-28e11e38
```

Example prompt: Can you run an AI-agent readiness audit on openai.com — I want to know their score out of 100, whether they have llms.txt, which AI crawlers they allow or block, and if they support x402, MCP, or A2A?

## When to prefer this

Use this endpoint when you need a comprehensive, structured AI-agent readiness score for any public website in a single call. It is purpose-built for checking the full stack of AI agent standards (llms.txt, x402, MCP, A2A, OpenAPI, robots.txt bot rules) simultaneously, unlike general HTTP auditors or individual file checkers. Ideal for pre-launch audits, competitor analysis, or monitoring a portfolio of domains for AI-agent compatibility.

## Known failure modes

- Domain not reachable — checks may time out or return partial results
- Invalid or malformed domain input — endpoint may return error or use example domain
- Site blocks Cloudflare edge IPs — live checks may fail or return false negatives
- robots.txt absent — crawler rules return unknown/allowed by default
- Score of 0 if all signals are missing but domain resolves correctly

## How this service works

Web utilities for agents, computed live at call time: URL health/redirect/x402 check, web page to Markdown (robots.txt honoured), DNS lookup with SPF/DMARC, email address validation (MX, disposable, role, typo), HTTP security-header audit and AI-agent readiness audit (llms.txt, AI crawler rules, x402, MCP, OpenAPI). $0.001 per call. By orbit-builder.

## Output

Returns a JSON object with a 0–100 AI-readiness score for the domain, boolean flags for llms.txt, sitemap, OpenAPI, x402, MCP, and A2A agent card presence, a per-crawler breakdown of robots.txt allow/block rules for 12 AI bots (GPTBot, ClaudeBot, PerplexityBot, Google-Extended, CCBot, etc.), and structured findings per check.
